左C-rpp半群的若干特征

CHARACTERISTICS OF LEFT C-rpp SEMIGROUPS

证明了左Ｃ－ｒｐｐ半群与左零带和左消幺半群的直积的半格是同一类半群，利用ＳＲＬＣＭ—半群给出了左Ｃ－ｒｐｐ半群类似于左Ｃ－半群相应结果的六条特征．

We prove that the class of left C-rpp semigroups coincides with the class of all semigroups which are semilattices of direct products of left zero bands and left cancellative monoids.Six characteristics of left C-rpp semigroups analogous to the corresponding results on left C-semigroups are given by using SRLCM-semigroups.
